Starting a thread on this because it keeps coming up in ones and twos: The countdown method that worked for me
Before anyone says it: yes, I have an appointment booked. I would still like to hear from people who have had this.
I am aware some of this may be nothing. I would still like to know whether other people have had it, because I have spent a fortnight assuming I am the only one.
What I would find most useful is not advice. It is somebody describing what their version of this was, and how long it went on for.
I will report back either way, because I have been helped by other people's follow-ups more than by their questions.
